JOHN KANE, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 245,383, dated August9, 1881.

Application filed June 6, 1881.

To all whom it may concern:

Be it known that I, JOHN KANE, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State ofPennsylvania,haveinvented a new and useful Automatic Fire-Extinguisher,of which the following is a specification.

Hy invention relates to improvements in automatic fire-extinguishers, inwhich the heat of a burning building acts upon a combustible orexplosive cartridge and opens a water-cock to irrigate theinterior ot'the building. I attain this object by a mechanism illustrated in theaccompanying drawings, in which Figure 1 is an elevation of the entiremachine. Fig. 2 is a vertical section of the complete extinguisher; andFig. 3 is a top view of the collar, showing the arms in site, two ofwhich are in section.

Similar letters refer to similar parts throughout the several views.

The thread 0 on the cap A secures the machine to a water pipe or main.This cap Ais secured to a second perforated cap, B, by a thread. The capA has a socket, h, which receives the head of the valve (1. The cap Bhas a milled rim, I, by which it is adjusted to regulate the valve 0.This cap B is perforated by a hole, L, through which passes the valverodD, and it admits of a column of water in addition. Theportion or cap Bextends through the collar E and rests on the base of the arm G, intowhich itis screwed. The collarE swings freely about the elongatedportion of the cap 13, resting upon the base of the arm G. The portion Bis perforated by an opening, L, running longitudinally through it, andopening by the holes 1) into the space M.

The collar E has a hollow center or space, M, and is provided withradiating arms F and F, four in number, which are perforated along theirentire length. The extreme tip is closed by a plug, and a slot, d, iscut horizontally in the side of each arm its entire length, for theegress of water. These arms are set so that two of them will have theslot on the outer curve of the arm and the other two will have the sloton the inner curve of the arm, the object of which arrangement is tospread the water more uniformly over any given surface,

(ModeL) the arm having the slot on the greater curve throwing the waterto a greater distance, while the arms with the slot on the lesser curvethrow the water to a less distance,or near the center of the circle ofirrigation.

The arm G has a forked projection, 2, into which is secured the cap endof a metallic cartridge, H. The ball of this cartridge H is perforatedwith a hole, and is slipped onto the rod I. This rod I is secured to thevalve-rod D by a collar, J, and set-screw c.

The mechanism operates as follows: The cap A is screwed into awater-main, which makes a connection between K and the column of waterin the main. The metallic cartridge H is then adjusted to the arm G andfitted to the pin I. The head of the valve 1'- is brought up against thevalve-seat h h, and the collar J clamped by the setscrew 0, which holdsthe valve 2' i in contact with the seat h h and prevents the flow ofwater. When a tire occurs the cartridge H, which is filled with materialwhichis easily explosive, explodes, which drives the valve-rod D andvalve 1' 2' down and opens the watermain K. The water then fills thechamber 0, rushes through L, and emerges through the openingsbinto thespaceM; thence it rushes through a into the hollow arms F and F, and bya reverse pressure sets them rotating, which spreads a spray of water inall directions, irrigating the space beneath it for many feet.

I do not claim the broad principle of a r0 tary automaticfire-extinguisher; but

What I do claim, and desire to secure by Letters Patent, is-

1. The combination of a cap, A, with a cap or plug, B, having a collar,E, provided with hollow arms F and F, an arm, G, carrying a cartridge,H, with a pin, I, and collar J attached to the valve-rod D, allsubstantially for the purpose and as described.

2. The metallic cartridge H, combined with the arm G, and pin I, andcollar J, all for the purpose and as described.
